Definitions

  • the present disclosure relates to a hollow fiber membrane cartridge and a hollow fiber membrane module including the same.
  • a fuel cell is a power generation cell wherein hydrogen is combined with oxygen to generate electricity.
  • Such a fuel cell has advantages in that it is possible to continuously generate electricity as long as hydrogen and oxygen are supplied thereto, unlike a general chemical cell, such as a dry cell or a storage cell, and in that there is no heat loss and thus, the efficiency of the fuel cell is about twice as high as the efficiency of an internal combustion engine.
  • the fuel cell directly converts chemical energy generated by combination of hydrogen and oxygen into electrical energy, and thus, the volume of a pollutant that is discharged is small. Consequently, the fuel cell has advantages in that it is environmentally friendly and concerns about depletion of resources due to an increase in energy consumption may be reduced.
  • such a fuel cell may be generally classified as a polymer electrolyte membrane fuel cell (PEMFC), a phosphoric acid fuel cell (PAFC), a molten carbonate fuel cell (MCFC), a solid oxide fuel cell (SOFC), or an alkaline fuel cell (AFC).
